[School of Natural Sciences PhD Scholarships] Models of buoyancy driven slope winds

About the project

About the Project This project will investigate instability mechanisms within stratified environmental flows, specifically focusing on 'katabatic winds' – these are downslope currents driven by nocturnal cooling of sloping terrains. These flows are prone to instabilities manifesting as downslope propagating waves or elongated vortices[1]. We seek a highly motivated PhD candidate to explore the evolution of these perturbations and address key questions regarding: The impact of nonlinearity on primary wave/vortex instabilities. The potential for secondary instability within developing nonlinear vortex structures. The coupling between wave and vortex mechanisms leading to sustained, nonlinear flow states in limiting cases. This research will employ a combined approach leveraging analytical techniques, asymptotic methods, and numerical simulations. Candidates should possess a strong mathematical foundation, interest in fluid mechanics/geophysical flow, and enthusiasm for interdisciplinary problem-solving. This project is expected to start in September 2027. Before you apply: We strongly recommend that you contact the supervisors for this project before you apply.
